6 General Information The COD165 thermoreactor will hold 25 round glass vials with 16 mm external diameter. It is designed for sample preparation in determining COD, total phosphorus, total nitrogen, total chromium and other parameters in water and sludge analysis. The COD165 thermoreactor, paired with the Thermo Scientific Orion COD reagents and the Thermo Scientific Orion AQUAfast AQ4000 advanced colorimeter or Thermo Scientific Orion AQUAfast AQ2040 colorimeter, provide the user with a complete analytical setup for COD analysis. The Thermo Scientific Orion AQUAfast AQ3700 colorimeter also performs COD analysis, as well as nitrogen and phosphate digestion methods. The COD165 thermoreactor is designed to be highly resistant to chemical and mechanical corrosion. The heating block that holds the COD vials allows for very good thermal homogeneity at the selected temperatures. The temperature of the heating block is microprocessor controlled. The Pt100 temperature probe does not require any calibration, because when the instrument is turned on, a self test is performed. The COD165 thermoreactor is equipped with a voltage selector for either 115 V or 230 V. It is accessible on the rear panel of the instrument. Always check the voltage setting before plugging the instrument into a power outlet. The COD165 thermoreactor has five preset work temperatures of 100 C, 120 C, 150 C, 160 C and 165 C and four preset run times of 30 minutes, 60 minutes, 120 minutes or continuous time. The heating block is equipped with over-temperature protection by a thermostat, which turns off heating when the temperature exceeds 180 C. Note: The COD165 thermoreactor is delivered complete with three power cords; one for 110 to 120 V standard US outlets, one for 220 to 240 V European outlets and one for 230 V Chinese outlets. 2 Thermo Scientific Orion COD165 Thermoreactor User Guide

7 Assembly and Installation Connecting the Power Supply The instrument is equipped with a voltage selector, which allows the connection to either 115 V or 230 V outlets. After unpacking the unit, position it correctly on the laboratory bench. Before connecting it to the power supply, check that the power switch is turned to 0 and check that the data on the unit s plate corresponds to that supplied by the electric socket. The unit works at voltages between 90 and 260 V with a frequency of 50 or 60 Hz. Note: The power switch means that the unit can be completely disconnected from the power supply when it is not in use, thus reducing energy consumption. Start Up Use the power switch on the front of the unit to turn the unit on (turned to ). When it is switched on, all the LEDs on the unit blink for few seconds. When the LEDs are off, the unit is ready to be programmed at different work temperatures and times. Operation Controls Control Power Switch Start/Temp Key Time Key Temperature LED Time LED Description The switch lights up when the instrument is turned on. When the Start/Temp key is pressed, the work cycle is started with the selected temperature and time values, which are indicated by their corresponding LEDs. To change the temperature, press the Start/Temp key and select desired temperature. The temperature setting will scroll down through the four temperatures and the corresponding LED will light. Note: It is possible to select different temperatures if the programmed temperature has not been reached and the timer is not started. Once timer has started this key is not operative. If the selected temperature is lower than the actual temperature of the heating block when the Start/Temp key is pressed, the cycle will not start and all the LEDs will turn on intermittently, indicating an error. To correct this error, select a higher temperature setting or allow the block to cool to a temp below the set point temperature. The timer starts when the block reaches the selected temperature. While the timer is running, the LED will blink and the Time key is not operative. When the instrument is turned on the temperature LEDs are not lit. Once the Start/Temp key is pressed, the selected temperature LED will light. All four LEDs will blink if the selected temperature is lower than the current block temperature. When the instrument is turned on the time LEDs are not lit. Select the desired run time by pressing the Time key. A blinking time LED indicates that the timer has started.

8 When the unit is switched on, press the Start/Temp key to start the work cycle. The default option is set at 160 C and 30 minutes, as shown by the corresponding LED. To select a different temperature, press the Start/Temp key until the corresponding LED is lit. To select a different time, press the Time key until the corresponding LED is lit. Note: It is possible to modify both temperature and time until the temperature of the heating block reaches the selected temperature and the run time starts. When the selected temperature is reached, a beeper will sound intermittently for 5 seconds. At this time the LED corresponding to the selected time will start to blink, signalling that the countdown has started. The end of the countdown will be signaled by a beeper that will sound continuously for 5 seconds; at the same time the heating element and the corresponding time and temperature LED will turn off. The instrument is now ready for a new work cycle. Power Interruptions The instrument will register a black out or a lack of power supply as a manual stop of the cycle. The work cycle will have to be restarted. Auto Shutoff Feature The COD165 thermoreactor will shut down once the timer cycle is complete. If the power to the instrument is interrupted, the instrument will automatically end the program that is running and a manual restart is required. Safety Features The COD165 thermoreactor is equipped with an internal thermostat that will not allow the temperature of the block to exceed 180 C. If this temperature is reached the unit will automatically shutdown. The COD165 thermoreactor continuously monitors the block of temperature and if inconsistent or anomalous readings are observed, the instrument will go into an alarm mode in which all eight LEDs blink and a beeper sounds.

9 Chapter 2 Operation Running a Cycle To initiate a cycle on the COD165 thermoreactor, power on the instrument and press the Start/Temp key. The default settings are a temperature of 165 C and a run time of 30 minutes, which will be indicated with the temperature and time LEDs. Use the Temp or Time key to change the temperature or time setting. The selected temperature and time settings are shown by the temperature and time LEDs. It is possible to change both the temperature and time if the selected temperature has not been reached yet and the timer has not started. Once the selected temperature has been reached, a beep will sound intermittently for five seconds. After the beep, the LED corresponding to the selected time will start to blink, indicating that the timer has started. The end of the cycle will be indicated when the beeper sounds continuously for five seconds. At the completion of the cycle, the heater is turned off and the temperature and time LEDs turn off. A new cycle can be run if the temperature of the heating block is not greater than the new selected temperature. If this occurs, the instrument will enter an alarm mode and all of the temperature LEDs will illuminate. Thermo Scientific Orion COD165 Thermoreactor User Guide 5

10 Maintenance All the maintenance operations should be performed only after the instrument has been disconnected from the power supply. The COD165 thermoreactor is designed to be maintenance-free and only occasional cleaning needs to be performed with a damp cloth and nonflammable, non-abrasive detergent. Replacing the Fuses The heating block is equipped with two fuses connected to the socket, located on the rear panel. If a fuse replacement is required, the power supply should be removed and then the fuse panel can be opened with a screwdriver. See the Electrical Schematic section for the fuse type. Disposing of the Instrument Disposal of this unit should comply with all local, state, and federal regulations. Verification of the Heating Block Temperature The electronic temperature controls within the COD165 thermoreactor are designed to provide excellent stability and eliminate temperature overruns or oscillations. The temperature sensor does not require calibration, as a self-calibration is performed upon power up of the instrument. The temperature may be monitored using a standard NIST traceable thermometer with a range of 0 to 250 C. Place the thermometer in a hole within the heating block and monitor the temperature.
